Challenges & solutions: The false sunflowers in this bed and nearby are susceptible to red aphids. To deal with them, we use a soapy water spray to weaken them and then wipe them away with a rag.
The false sunflowers also tend to grow tall with thin stalks, staking helps with this and a cut back in mid spring can help produce a hardier stems (though it delays blooming by a few weeks).
